Code Review
This pull request updates the .ci.yaml configuration to pin the os property of the basic_material_app_macos__compile target to Mac-26.6 due to benchmark differences during the macOS fleet transition. There are no review comments, and I have no feedback to provide.

Follow-up to flutter#194813 for flutter#194809. `basic_material_app_macos__compile` has the same problem we already fixed for `flutter_gallery_macos__compile` and `hello_world_macos__compile`: the Mac_benchmark fleet is split between macOS 15 and macOS 26, and the two produce binaries of different sizes. Its `release_size_bytes` keeps flipping by about 69KB depending on which bot runs the task, so the perf dashboard keeps firing alerts for it (75 of the 94 untriaged regressions right now). Since flutter#194813 landed, the two pinned targets have stopped flipping. `basic_material_app_macos__compile` hasn't: it has jumped by more than 20KB 62 times since then. This pins it to `Mac-26.6` in the same way. I didn't find this flipping in any other size metric on Mac hosts. The iOS compile tests (`*_ios__compile`, `imitation_game_flutter__compile`) look stable. ## Pre-launch Checklist - [x] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [x] I read the [AI contribution guidelines] and understand my responsibilities, or I am not using AI tools. - [x] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [x] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [x] I signed the [CLA]. - [x] I listed at least one issue that this PR fixes in the description above. - [x] I updated/added relevant in-code documentation (doc comments with `///`). - [x] If this PR introduces a new feature or capability, I created and linked a website documentation issue or PR in [flutter/website] (or verified none is needed). - [x] I added new tests to check the change I am making, or this PR is [test-exempt]. - [x] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [x] All existing and new tests are passing.
